Scale-up of Nanoparticle Synthesis by Flame Spray Pyrolysis: The High-Temperature Particle Residence Time

“…The specific surface area (SSA) of product zirconia nanoparticles was determined by nitrogen adsorption at 77 K (Micromeritics Tristar 3000) after degassing in nitrogen at 200 °C for at least 1 h. The primary particle diameter was calculated as d p = 6/(ρ p SSA) assuming monodisperse spheres (BET-equivalent diameter) and employing a density of ρ p = 5.72 × 10 3 kg/m 3 for tetragonal zirconia . The powder crystallinity was determined by X-ray diffraction (XRD; Bruker D8 Advance, 40 kV, 40 mA, Cu Kα radiation, Bragg–Brentano geometry) in the range of 2θ = 20–70°.…”

Mass-mobility characterization of flame-made ZrO2 aerosols: Primary particle diameter and extent of aggregation

“…Here, multiple charge effects might not be relevant as only the average mass for a given mobility diameter, d m , is extracted (please see Appendix 6.1 for an example calculation). From the density of tetragonal zirconia ( ρ = 5.72·10 3 kg/m 3 ) [17], the solid agglomerate or aggregate volume v is estimated from its measured mass. The number concentration is measured after the APM analyzer with a condensation particle counter (CPC, Model 3775, TSI Inc.).…”
